The constant search for the proper management of non-degradable waste in conjunction with the circular economy makes the thermal pyrolysis of plastics an important technique for obtaining products with industrial interest. The present study aims to produce pyrolytic oil from thermoplastics and their different mixtures in order to determine the best performance between these and different mixtures, as well as to characterize the liquid fraction obtained to analyze its use based on said properties. This was carried out in a batch type reactor at a temperature of 400 °C for both individual plastics and their mixtures, from which the yields of the different fractions are obtained. The liquid fraction of interest is characterized by gas chromatography and its properties are characterized by ASTM standards. The product of the pyrolysis of mixtures of 75% polystyrene and 25% polypropylene presents a yield of 82%, being the highest, with a viscosity of 1.12 cSt and a calorific power of 42.5 MJ/kg, which has a composition of compounds of carbon chains ranging between C6 and C20, for which it is proposed as a good additive agent to conventional fuels for industrial use.
不断寻求妥善管理不可降解废物与循环经济相结合，使得塑料热解成为获得具有工业利益的产品的重要技术。本研究旨在从热塑性塑料及其不同混合物中生产热解油，以确定这些和不同混合物之间的最佳性能，以及对获得的液体馏分进行特性分析，根据这些特性来分析其用途。这是在 400°C 的间歇式反应器中对单一塑料及其混合物进行的，从中获得不同馏分的产率。通过气相色谱法对感兴趣的液体馏分进行了表征，并根据 ASTM 标准对其性质进行了表征。75%聚苯乙烯和 25%聚丙烯混合物热解的产物产率最高，为 82%，具有 1.12 cSt 的粘度和 42.5 MJ/kg 的热值，其组成化合物的碳链介于 C6 和 C20 之间，因此它被提议作为一种良好的添加剂，用于工业用途的常规燃料。
